For each of the new verbs presented (querer, poder, poner, saber, venir) write two sentences for each form of each of the verbs in the preterite form. Example: for querer write 2 sentences in the "yo" form. 2 sentences using tú, 2 sentences for the shared ella, ud form, 2 sentences using nosotros, 2 using vosotros and 2 using uds/ellos/ellas shared form.

Then do the same thing for poder, then poner, saber, and venir.

Be sure they are complete sentences, including a pronoun, and that they make sense. Don't worry about the vosotros form. You should have 50 sentences when you are finished.
